The Hanoi police have already busted three cases in Hoang Mai in the past few days and thousands of illegally imported mooncakes have been confiscated. All of them were stuffed with melted eggs which is the current trend across online shopping websites and priced at 6.5 to 11 US dollars per box. The police said these mooncakes were illegally imported from China via Lao Cai for only one-third of their selling price and didn't pass through any food hygiene examinations.
